Active clinical trials for "Coronary Artery Disease"

This multicentre, open-label, single-arm Study is to evaluate the effect of Rosuvastatin 20 mg 76 weeks on coronary atherosclerosis plaque versus baseline in Chinese coronary heart disease (CHD) patients with hyperlipidemia by measuring the plaque volume using a 64 slice spiral CT. Effect on blood lipids, hsCRP and Carotid intima-media thickness (CIMT) is also evaluated.

RATIONALE: Transradial coronary stenting is associated with less risk of access site complications and bleeding compared to femoral approach. Major bleeding post-PCI is a strong independent predictor of mortality and MACE. Depending of the antithrombotic regimen and access-site used, bleeding related to access-site represents 50-80% of the cases. Whereas transradial approach minimizes the risks of access-site bleeding, it has no impact on non-access site bleeding. Peri-procedural anemia is also an independent predictor of mortality and MACE. With femoral approach, bivalirudin compared to heparin ± glycoproteins IIb-IIIa has been associated with a significant reduction in access-site and non-access site related bleeding. In a post-hoc analysis of patients treated by transradial approach in ACUITY, there was a trend for non-access site bleeding (organ bleeding) with bivalirudin compared to heparin ± glycoproteins IIb-IIIa. HYPOTHESES: In patients at high-risk of peri-procedural bleeding, bivalirudin ± glycoproteins IIb-IIIa reduces the risk of bleeding compared to heparin ± glycoproteins IIb-IIIa. In patients at high-risk of bleeding and undergoing transradial PCI, bivalirudin significantly reduces the incidence of non-access site bleeding and peri-procedural anemia.

The main objective of this study is to assess the safety and effectiveness of the TiN-coated MAR-Tyn stent in maintaining minimum lumen diameter in de novo native coronary artery lesions as compared to an uncoated control cobalt-chromium balloon-expandable stent (Vision, Abbott Vascular). Both stents are mounted on a Rapid Exchange Stent Delivery System.

Cardiac resynchronization therapy has been shown to be effective in reducing symptoms and mortality in heart failure patients. However, very few is known about the importance of the left ventricular pacing site. We study in a random order 11 different left ventricular pacing sites and compare their hemodynamics using pressure-volume catheters. The consequences on the surface ECG are also assessed.

The field of secondary prevention remains an extremely important goal for diagnostic and therapeutic approaches keeping in mind that 40% of all patients with acute myocardial infarction have prediabetes, commonly as impaired glucose tolerance, which has not been known and treated and for which there are no guidelines for treatment. In this context, accumulating evidence shows beneficial effects for treating diabetes mellitus early in the course of disease, whereas other evidence shows that aggressive antidiabetic therapy may be associated with undesired risks. Accordingly, the present randomized and controlled pilot study is designed as hypothesis creating study to create first data about potential medication in early type 2 diabetes including impaired glucose tolerance of patients with known coronary artery disease as means of secondary prevention by comparing oral antidiabetic therapy with metformin with insulin glargine o.d. and by studying the respective effects on cardiovascular function and metabolism both in the fasting state and after a standardized meal. As diastolic myocardial function has emerged as important prognosticator, the hypothesis was tested that treatment with insulin glargine improves myocardial function in patients with coronary artery disease and newly diagnosed type 2 diabetes including impaired glucose tolerance.

Should we, or should we not, perform dilatation of the side branch through the main vessel stent, if there is acceptable blood flow in the side branch?

The purpose of this study is to determine whether a new cerebral oxygenation monitoring device is comparatively similar to the current approved devices.

Restenosis due to neointimal hyperplasia causes repeat target vessel revascularization in a relevant number of patients undergoing percutaneous coronary interventions (PCI). Drug-eluting stents (DES) are currently adopted to reduce the rate of restenosis; however, they may increase risk of stent thrombosis. Experimental data and first clinical experiences showed that inhibition of neointimal hyperplasia may be obtained by local administration of anti-proliferative drugs (like paclitaxel) loaded on the surface of angioplasty balloons. Data on the efficacy of novel coronary drug-eluting balloons (DEBs) are lacking. Aims of this open label prospective, randomized trial is to evaluate neointimal hyperplasia in patients undergoing bare-metal stent (BMS) implantation alone compared to those receiving additional DEB use and to assess if the technique of DEB use may affect the degree of neointimal hyperplasia. Neointimal hyperplasia will be assessed by Optical coherence tomography (OCT).

The experimental design is a multi-center, prospective, non-controlled, non-randomized, single-arm clinical registry trial. The study will enroll 5,000 patients who receive the Firebird2TM Cobalt-ChromiumAlloyed Sirolimus-Eluting Stent implantation. For patient with multivessel disease, only Firebird 2TM Stent will be implanted. The enrollment of patients will take about 4 months. Clinical follow-up will be at 30 day, 6 month, 12 month, 24 month and 36 month. Patients withdrawing the study due to any reasons will not be replaced.

The prospective, randomized, two centre study investigates acute cerebrovascular events during extracorporal circulation and the early post operative outcome when using either the minimized cardiopulmonary bypass circuit (ROCsafeTM) or a standard cardiopulmonary bypass circuit in patients undergoing coronary artery bypass grafting.
